          bgcolor
              When there is no colorscale sets the color of
              background pattern fill. Defaults to a `marker.color`
              background when `fillmode` is "overlay". Otherwise,
              defaults to a transparent background.
          bgcolorsrc
              Sets the source reference on Chart Studio Cloud for
              `bgcolor`.
          fgcolor
              When there is no colorscale sets the color of
              foreground pattern fill. Defaults to a `marker.color`
              background when `fillmode` is "replace". Otherwise,
              defaults to dark grey or white to increase contrast
              with the `bgcolor`.
          fgcolorsrc
              Sets the source reference on Chart Studio Cloud for
              `fgcolor`.
          fgopacity
              Sets the opacity of the foreground pattern fill.
              Defaults to a 0.5 when `fillmode` is "overlay".
              Otherwise, defaults to 1.
          fillmode
              Determines whether `marker.color` should be used as a
              default to `bgcolor` or a `fgcolor`.
          shape
              Sets the shape of the pattern fill. By default, no
              pattern is used for filling the area.
          shapesrc
              Sets the source reference on Chart Studio Cloud for
              `shape`.
          size
              Sets the size of unit squares of the pattern fill in
              pixels, which corresponds to the interval of repetition
              of the pattern.
          sizesrc
              Sets the source reference on Chart Studio Cloud for
              `size`.
          solidity
              Sets the solidity of the pattern fill. Solidity is
              roughly the fraction of the area filled by the pattern.
              Solidity of 0 shows only the background color without
              pattern and solidty of 1 shows only the foreground
              color without pattern.
          soliditysrc
              Sets the source reference on Chart Studio Cloud for
              `solidity`.
